Top-quark mass from the diphoton mass spectrum

We calculate the \(gg\rightarrow \gamma \gamma \) amplitude by including the \(t\bar{t}\) bound-state effects near their mass threshold. In terms of the non-relativistic expansion of the amplitude, the LO contribution is an energy-independent term in the one-loop amplitude. We include the NLO contribution described by the non-relativistic Green function and part of the NNLO ...
